A plumbing shop's most likely claim is somebody's back. Its most expensive claim is water — and the water is almost never the expensive part. The expensive part is everything the water reached on its way down, discovered on a Monday morning after a long weekend.
Plumbing is one of the largest trades in the Statesboro, Savannah, Dublin, Vidalia, Swainsboro and Augusta corridor and one of the least well-served by generic contractor insurance content, because almost everything written for contractors is written around fall severity. Plumbing's severity is not a fall. It is a water loss inside a finished building, and it behaves so differently that a program built on contractor rules of thumb will usually be wrong in both directions at once — too much attention on the jobsite and not nearly enough on what happens after the crew drives away.
If you also install and service heating and cooling equipment, read this alongside HVAC and mechanical contractors. If a growing share of your work is sewer laterals and mains in the street rather than in the building, the more relevant page is water and sewer main contractors, and the excavation exposure is covered in more depth under excavation and earthmoving.
| Line | What drives it on a plumbing account |
|---|---|
| Workers comp | Usually the biggest premium line. Middle of the contractor ladder — below roofing, steel and line work, above painting and finish trades. Rated per $100 of payroll by class. |
| General liability | Carries the severity, and the severity is water. Rated on payroll or receipts depending on carrier and state. See GL cost for the trades. |
| Commercial auto | Heavier than most trades, because service plumbing is a fleet business. Trucks moving all day, all territory, often with a new tech driving. |
| Tools & equipment | Cameras, jetters, locators, threading machines and press tools live in trucks overnight. Theft is the claim. See tools and equipment floater. |
| Installation floater | Fixtures, water heaters and materials staged on a site you do not own. Not covered by your GL. See installation floater. |
| Umbrella | Often required by contract before it is wanted. Also the line that catches a four-floor water loss. See umbrella cost. |
A standard liability form excludes damage to your product and damage to your work. On a plumbing job that means the fitting, the joint, the line you ran and the labor to open the wall and do it again are generally your cost. What the policy is built to answer for is the damage the escaping water did to everything else: drywall, ceilings, flooring, cabinetry, millwork, electrical, electronics, tenant contents, and the loss of use of the space while it dries.
That is why the severity profile of a plumbing account looks nothing like its payroll. The claim size is not set by the size of your job. It is set by what is beneath your work and how long the water ran. A supply connection on a fourth-floor riser can produce a claim on all four floors. The same fitting in a slab-on-grade warehouse produces almost nothing.
Classification systems generally separate plumbing performed in connection with new construction from plumbing service, repair and remodeling in existing structures. Both are separate again from water, sewer and gas main installation in the street, from septic and drain-field work, from fire sprinkler installation, and from mechanical work where the same crew sets equipment and runs duct.
A shop carrying one class for everything is a routine finding, and it can be wrong in either direction:
The related trap is the mixed crew: where payroll records do not support a division between classes, rating rules generally assign the payroll to the highest-rated class applicable. See how class codes get assigned and what to expect at an audit. Rules are set by the applicable rating bureau and state authority and are amended — confirm with your carrier.
The frequency layer is unglamorous and it is where the experience modifier comes from:
Two categories carry the genuinely catastrophic potential, and underwriters treat both as pricing and appetite questions:
Sewer lateral, water service and main work puts people in a hole. Collapse is the classic fatality mechanism in this trade, and the depth question — along with the protective systems actually used at that depth — is an underwriting question, not a safety footnote.
Manholes, lift stations, vaults, tanks, pits and tight crawl spaces carry an atmospheric hazard including hydrogen sulfide and oxygen deficiency. The defining feature of these events is that they take the would-be rescuer as often as they take the first entrant, which is why carriers ask about entry procedures, atmospheric testing and rescue arrangements specifically. Excavation, confined space, respiratory protection and recordkeeping requirements are set by federal and state authority and are amended.
Soldering, brazing and open-flame work inside an occupied or finished structure is a recognized ignition source, and the claim pattern is consistent: the fire does not start at the joint. It starts in concealed combustible material, insulation, dust, framing or void space next to the joint — and it is discovered after the crew has left.
Carriers respond to this in one of three ways, and it is worth knowing which one applies to you:
The practices underwriters expect are worth adopting regardless: a written permit per instance, combustibles removed or protected within a defined radius, a charged extinguisher or hose at the point of work, a designated fire watch during the work, and a continued watch plus a later re-check of the area after work stops. Where press fittings, mechanical joints or cold methods can replace torch work in finished space, carriers notice — and so does the claim record.
Plumbing installs concealed systems that fail on their own schedule. A repipe, a slab run, a supply line behind a wall, a heater connection, a drain pitch, a gas line or a backflow assembly can sit quietly for years and then produce a loss. Completed operations is the coverage that answers for it, and five things follow:
Service plumbing runs a fleet, and the fleet is frequently the second-largest line on the account. Three items drive it: vehicle count and radius, driver records, and whether anyone is checking the MVRs of the techs hired last spring. Add the trailer, the jetter and the excavator if you own one, and be honest about who takes a truck home and who else drives it — see hired and non-owned auto and commercial auto symbols, which is the page that explains why your policy may not cover a vehicle you assumed it did.
Two more worth a look on a plumbing account: contractor's pollution liability, which matters the moment you touch sewage, septic, fuel lines, backflow and cross-connection, or a chemical drain program; and wire-transfer fraud coverage, because shops that invoice GCs for six-figure progress payments are a standing target.
We are an independent agency in Statesboro placing every line a plumbing contractor carries — comp, GL, auto, property, inland marine, umbrella and cyber — through one person, so nobody has to coordinate three agents when a water claim crosses two policies. The first review on a plumbing account is short and specific: whether the classification still matches the actual work mix, whether the policy carries a hot-work condition or exclusion, whether completed operations has a gap in it, and whether the umbrella limit reflects what sits underneath the buildings you work in. More on how we work: Statesboro and Savannah. If you bid municipal, school or utility work that requires a bond, our sister brand BettrBonds handles that side.
Send your comp declarations with classifications and payroll, your GL declarations including the products and completed operations aggregate, your auto schedule and your umbrella. We'll tell you whether the class still matches the work, whether there is a hot-work condition or water-damage sublimit on the form, whether your completed operations has a gap from your last carrier change, and whether your limits reflect the buildings you actually work in.
Get a free coverage reviewPlumbing sits in the middle of the contractor comp ladder — generally below roofing, structural steel and overhead line work, above painting, flooring and finish carpentry — because it combines moderate injury frequency with relatively low catastrophic fall exposure. Comp is usually the largest line, rated per $100 of payroll by class. GL is rated on payroll or receipts depending on carrier and state and carries a disproportionate share of the severity, because the loss that hurts is water escaping into a finished building rather than a jobsite injury. Commercial auto is heavier than most trades because service plumbing is a fleet business. The variables: the mix between service, residential new construction, commercial and institutional work, and underground sewer or water main work, which are frequently different classes; excavation depth; whether the shop does gas piping, medical gas, fire sprinkler, backflow testing or septic; payroll and receipts; subcontractor use and certificate discipline; vehicle count, radius and driver records; and losses read claim by claim.
Generally yes as to the building and its contents, and generally no as to your own work. The standard form excludes damage to your product and damage to your work, so the failed fitting and the labor to open the wall and redo it are normally on you. What the policy answers for is what the water damaged on its way — drywall, flooring, cabinetry, ceilings, electrical and electronics, tenant contents and loss of use. Because that number is driven by what the water reached rather than by job size, a thirty-dollar fitting on a fourth-floor riser can produce a claim across every floor beneath it. Several provisions decide how it actually resolves: some policies carry a water damage exclusion or sublimit for certain operations, some carry a subcontractor warranty, sudden and accidental discharge is treated differently from gradual seepage in nearly every form, and completed operations is what responds after the job is finished and accepted.
Commonly yes, and it matters in both directions. Classification systems generally separate plumbing in connection with new construction from service, repair and remodeling in existing structures, and both from water, sewer and gas main installation in the street, from septic and drain-field work, from fire sprinkler installation, and from mechanical work where the crew also sets equipment and runs duct. A service shop misclassified into a construction class may be overpaying materially; a shop that has quietly added sewer lateral replacement, main line work or directional boring to a service business is carrying a hazard nobody underwrote. Where payroll records do not support a division between classes, rating rules generally assign payroll to the highest-rated class applicable.
Strains and sprains lead on count — cast iron, water heaters, fixtures, pipe, crawl spaces, attics, confined positions — and they run long, which matters because the experience modifier responds to duration more than count. Then lacerations from cutting, threading and deburring; eye injuries from cutting, grinding and chemical drain cleaner splash; burns both thermal from torch and hot lines and chemical from drain products and flux; and falls from ladders, ceiling access and unfinished floor openings, which is where the serious claims live. Two categories carry catastrophic potential: trench and excavation collapse during sewer lateral, water service and main work, and confined space entry into manholes, lift stations, vaults, tanks and crawl spaces, where hydrogen sulfide and oxygen deficiency take would-be rescuers as often as first entrants.
Usually not a separate policy, but the exposure must be disclosed and is frequently the subject of a specific policy condition. Soldering, brazing and torch work in occupied or finished structures is a recognized ignition source, and the fire generally starts not at the joint but in concealed combustible material, insulation, dust, framing or void space adjacent to it, discovered after the crew leaves. Carriers respond three ways: a hot work condition or warranty requiring specific practices as a condition of coverage, an exclusion for loss arising from torch, welding or open flame work, or silence with the exposure priced in. Confirm which applies in writing. The expected practices are a written permit per instance, combustibles removed or protected within a defined radius, a charged extinguisher or hose at the point of work, a designated fire watch during the work, and a continued watch and later re-check after work stops.
Because plumbing installs concealed systems that fail on their own schedule — a repipe, a slab run, a supply line behind a wall, a heater connection, a drain pitch, a gas line or a backflow assembly can sit for years and then produce a loss long after the invoice was paid. Five consequences: the products and completed operations aggregate is a separate limit on most forms from the general aggregate; continuity matters, because a gap between carriers or a form with a retroactive restriction can leave finished work uninsured; owners and GCs increasingly require additional insured status extending to completed operations rather than ongoing operations only, which are different endorsements; any warranty in your own contract is a contractual obligation whose cost is generally not an insured loss; and on subcontracted work, a current certificate with the right wording and a waiver of subrogation where required is the difference between transferring a loss and absorbing it.
A breakdown of receipts and payroll across residential service, residential new construction, commercial and institutional new construction, remodel and tenant improvement, and underground sewer, water or gas main work — percentages, not adjectives. Maximum excavation depth and the protective systems used at that depth. The confined space program including entry procedures, atmospheric testing and rescue arrangements. The hot work permit program and whether press or mechanical joining has displaced torch work in occupied buildings. Whether the shop performs gas piping, medical gas, fire sprinkler, backflow testing or certification, septic and drain field, water treatment or any fire protection work, several of which are appetite rather than pricing decisions. The largest single job in three years and the largest in progress. Vehicle count by type, radius, MVRs for every driver and the written policy on personal use. Subcontractor practice including written agreements, certificates collected before work starts, and the actual indemnity and additional insured language. The contract documents signed for the largest customers. And three to five years of losses narrated claim by claim, with water damage claims separated from injury claims.
